Leached superabrasive elements and leaching systems methods and assemblies for processing superabrasive elements
A polycrystalline diamond element includes a polycrystalline diamond table having a body of bonded diamond particles with interstitial regions. A first volume of the body includes an interstitial material and a second volume of the body has a lower concentration of interstitial material within the interstitial regions than the first volume. The polycrystalline diamond element includes an element face and a peripheral surface. The first volume is adjacent to a central portion of the element face and the second volume is adjacent to the peripheral surface. A method of processing a polycrystalline diamond element includes forming a concave region in the polycrystalline diamond element, exposing at least a portion of the concave region to a leaching solution, and removing at least a portion of the polycrystalline diamond material that was exposed to the leaching solution from the polycrystalline diamond element.
